[求助]first编译错误

make: *** [main.o] 错误 127
这个错误是什么原因，感觉并没有相关提示

发现我的makefile里的编译器没改，改了之后又提示
root@ubuntu:/opt/EmbedSky/Qte/arm-qtopia-2.2.0/pro/first# make
make: *** 没有规则可以创建“main.o”需要的目标“/opt/EmbedSky/Qte/arm_qtopia-2.2.0/qtopia/include/qtopia/qpeglobal.h”。 停止。

我在makefile里删除了相关行只留下
main.o: main.cpp \
                first.h \
                /opt/EmbedSky/Qte/arm-qtopia-2.2.0/qtopia/include/qtopia/qpeapplication.h
编译继续出错

版主，什么原因呢

怀疑你第一次修改Makefile文件时多删除了编译选项所致。

这次严格按照手册上的修改还是报如下错误

很奇怪，我直接到arm－qtopia－2.2.0下first目录去make，还是出现如下错误，但是我编译arm－qtopia－2.2.0是完全通过的，且制作好文件系统烧录到开发板上，程序都是可以运行的

6楼的错误：arm-none-linux-gnueabi-gcc: main.o: No such file or directory，提示信息没有找到main.o，可能是没有main.c文件导致的，也可能是Makefile文件中写错了。
7、8楼的错误：如果你确认你的arm版本的qtopia2.2.0编译成功了的话，应该是你没有设置环境变量导致的错误哦。

仔细分析了arm-qtopia-2.2.0_build文件，然后分析了pro下的builed文件，发现编译这几个应用程序的时候，环境变量设置的是/opt/EmbedSky/Qte/arm-qtopia-2.2.0/. SetQteEnv
setQteEnv内容如下
#!/bin/sh
export QPEDIR=/opt/EmbedSky/Qte/arm-qtopia-2.2.0/qtopia
export QTDIR=/opt/EmbedSky/Qte/arm-qtopia-2.2.0/qt2
export TMAKEDIR=/opt/EmbedSky/Qte/arm-qtopia-2.2.0/tmake
export TMAKEPATH=$TMAKEDIR/lib/qws/linux-arm-g++
export PATH=$QTDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

而编译qt2.2.0时设置的setARM_QteEnv内容
#!/bin/sh

export QTDIR=/opt/EmbedSky/Qte/arm-qtopia-2.2.0/dqt
export TMAKEDIR=/opt/EmbedSky/Qte/arm-qtopia-2.2.0/tmake
export TMAKEPATH=$TMAKEDIR/lib/qws/linux-arm-g++
export PATH=$QTDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

为什么编译应用程序时qtdir是qt2，而编译qt2.2.0的qtdir是dqt呢？

qt2中的库才是我们需要的qte的库。Qt手册更新了，建议下载新版本的来看。
